Hi Kevin.

 I don`t think that is possible. But you can make your own paging control and that to the PageList like this PageList.PagingControl = customPager();

Just use Reflector on the EPiServer.dll and you will find the PagingControl under EPiServer.Web.WebControls.PagingControl. You only need to override the CreatePagingItems(PageDataCollection pages).

I have made my own pagingcontrol like this. Works like a charm :)

 BR,

Tore 

Hi, thanks for the tip, do you have a sample code you can post for me at all?

thanks 

Hi Kevin.

I have made a sample for you here. In the for loop, the page numbers are written out. You could either send you own text to AddSelectedPagingLink and the AddUnselectedPagingLink, or you can override them with you own code. Hope this helps you on your way :)

<code>

using System;
using EPiServer.Core;
using EPiServer.Web.WebControls;

namespace EPiServerSample.Templates.WebControls
{
public class CustomEPiPager : PagingControl
{
// Fields
private int _linkCounter;

private string Translate(string text)
{
return LanguageManager.Instance.Translate("/webcontrols/paging/" + text);
}

public override void CreatePagingItems(PageDataCollection pages)
{
int pagingIndex = CurrentPagingItemCount - 1;
bool visible = CurrentPagingItemIndex > 0;
bool flag2 = CurrentPagingItemIndex < pagingIndex;
if ((pagingIndex != 0) || !AutoPaging)
{
_linkCounter = 0;
if (FirstPagingItemText.Length > 0)
{
AddUnselectedPagingLink(0, FirstPagingItemText, Translate("firstpage"), visible);
AddLinkSpacing(visible);
}
if (PrevPagingItemText.Length > 0)
{
AddUnselectedPagingLink(CurrentPagingItemIndex - 1, PrevPagingItemText, Translate("prevpage"), visible);
AddLinkSpacing(visible);
}
for (int i = 0; i <= pagingIndex; i++)
{
if (i == CurrentPagingItemIndex)
{
AddSelectedPagingLink(i, Convert.ToString((int)(i + 1)), Translate("currentpage"));
}
else
{
AddUnselectedPagingLink(i, Convert.ToString((int)(i + 1)), string.Format(Translate("pagenumber"), i + 1), true);
}
if (i < pagingIndex)
{
AddLinkSpacing();
}
}
if (NextPagingItemText.Length > 0)
{
AddLinkSpacing(flag2);
AddUnselectedPagingLink(CurrentPagingItemIndex + 1, NextPagingItemText, Translate("nextpage"), flag2);
}
if (LastPagingItemText.Length > 0)
{
AddLinkSpacing(flag2);
AddUnselectedPagingLink(pagingIndex, LastPagingItemText, Translate("lastpage"), flag2);
}
}
}
}
}

</code> 

Here is AddSelectedPageLink and AddUnselectedPageLink if you need them. Just include them in your CustomEPiPager class and override them.  

<code>

protected virtual LinkButton AddSelectedPagingLink(int pagingIndex, string text, string altText)
{
LinkButton child = this.CreatePagingLink(pagingIndex, text, altText);
child.CssClass = CssClassSelected;
Controls.Add(child);
return child;
}

protected virtual LinkButton AddUnselectedPagingLink(int pagingIndex, string text, string altText, bool visible)
{
LinkButton child = this.CreatePagingLink(pagingIndex, text, altText);
child.CssClass = CssClassUnselected;
child.Visible = visible;
Controls.Add(child);
return child;
}

</code> 

Hi,

Thanks a lot for the code sample, it works great!

Just one small issue. When the next page button is pressed, the page data doesn't actually move forward, it just triggers a postback and the data stays the same. Then on the 2nd press, it moves forward as expected.

Is this a problem you've come across before?

Also, at which event of the page is it best to assign the custom paging class to the pagelist? I currently do it on pageinit, is this correct?

Thanks 

I've got the same problem
I need to click 2 times to move to the next 10 pages in my pagelist

 Any soloutions?

/jesper

I tested it out and got the same problem. I am not sure why this propblem accours, but you could try overriding more of the source(EPiServer.Web.WebControls.PagingControl).

I copied the whole code(EPiServer.Web.WebControls.PagingControl) from Reflector and got it to work. You should however just override the things you need. But this a way to start :)

BR,

Tore

Hmm ok
I've copied all code from pagingControl  but get this error

'EPiServer.Web.WebControls.PageListData' does not contain a definition for 'CurrentPagingItemIndex' 

/jesper

Which version of EPiServer are you using? Try leaving out the CurrentPagingItemIndex property.

<code>

  public virtual int CurrentPagingItemIndex
{
get
{
if (this._source == null)
{
return 0;
}
return this._source.CurrentPagingItemIndex;
}
set
{
this._source.CurrentPagingItemIndex = value;
}
}

</code> 

Tore 

I need CurrentPagingItemIndex to when I call the PagingItemChanged

I think my problem is the 'Source'

I set the pagingControl like this

PagingControl customPaging = new epiPager();
NewsPageList.PagingControl = customPaging;

Should I define the the dataSource for customPaging?

/jesper 

Hi Jesper.

But you will have access to the CurrentPagingItemIndex via the PagingControl class that you inherit from. I skipped the public virtual int CurrentPagingItemIndex, and it worked fine for me.

PageList.PagingControl = new epiPager(); should be fine.

 BR,

Tore 

Hmm yes...

but when I do I get "System.NullReferenceException: Object reference not set to an instance of an object" on this line: this.CurrentPagingItemIndex = num; 

in PagingItemChanged

/jesper

Hi Jesper.

Try to not override PagingItemChanged. As I said in my post earlier today, you should just override the things you need to override. So try to remove things one by one. I don`t think you need to override all the properties, but I have not had the time to try it out myself.

BR,

Tore 

Hi Tore,
Thanx for your time
I've tried to remove allmost everything but I get null reference error

I'm starting to think that  I've done something wrong in the start of my code

My code starts like this:

<code>

namespace hk.templates.WebControls
{
    public class epiPager : PagingControl
   {

    // Fields
    private int _linkCounter;
    private PageListData _source;

// Methods

    public epiPager()

   {

    }

   public epiPager(PageListData source)
   : this()
   {
       this._source = source;
       this._linkCounter = 0;
    }
</code>

It's not the same start as my customEpipager control I've made that works
Am I doing this wrong?

best regards

jesper 

Hi Jesper.

 I have made a new pager that not use postbacks at all and sets the CurrentPagingItemIndex by a querystring parameter. It also renders out <ul><li><ol> elements. I have tested this and it shoud work :)

Code for getting the querystring parameter

<code>

 ///
/// Gets the CurrentPagingItemIndex from the QueryString
///
/// The CurrentPagingItemIndex. If it doesn't exist, 0 is returned
protected static int GetItemIndex()
{
int num;
return ((HttpContext.Current.Request.QueryString["p"] != null) && (int.TryParse(HttpContext.Current.Request.QueryString["p"], out num))) ? num : 0;
}

</code>

Code for setting the pager on the list

<code>

 PageList.PagingControl = new Pager();
PageList.PagesPerPagingItem = (int)CurrentPage["ListCount"];
PageListList.PagingControl.CurrentPagingItemIndex = GetItemIndex(); PageList.PagingControl.FirstPagingItemText = "";
PageList.PagingControl.LastPagingItemText = ""; plList.PagingControl.CssClassPagingContainer = "pager";

</code>

Hope this solves your problem :)

BR,

Tore 

IT works great!!

thank you!

Hi Tony.

I am not sure why this happes. There got to be something we are forgetting to do. Maybe we should contact EPiServer and get them to look at it?

But if you look at the last example I have pasted in you will get a working custom pager :)

BR,

Tore 

Unfortunatly that woul dmean I would not be able to use it in an ajax update panel as it wouldnt catch the postback to update.

Hi Kevin.

 I do not think this is possible. But you could make your own CustomPageList that inhertits from PageList. Make your own ITemplates called HeaderPagingHeader and HeaderPagingFooter. Then override the CreateChildControls() and render out these  ITemplates before the ItemTemplate. Maybe you have to do something in PageListData.CreatePagingControls() to say that you want the pager rendered out in the new ITemplates as well as PagingHeaderTemplate and PagingFooterTemplate.

BR,

Tore 

Worked out a great way to display the pager on top as well as below the pagelist.

You just need to implement the Pagelist prerender event like this:

 protected void SearchResult_PreRender(object sender, EventArgs e)
{
    PageList pageList = (PageList)sender;

    StringBuilder builder = new System.Text.StringBuilder();
    StringWriter stringWriter = new StringWriter(builder);
    HtmlTextWriter writer = new HtmlTextWriter(stringWriter);
    pageList.PagingControl.RenderControl(writer);
    string html = builder.ToString();
    litTopPager.Text = html; //Literal control placed anywhere on the page.

}

Then, most importantly, you need to override an event on the Page base class like this:

 public override void VerifyRenderingInServerForm(System.Web.UI.Control control)
{

}

I've implemented a baseclass that inherits from the EpiServer template class, andput this there.

What it does is overrides the validation error caused  by the pagerender when you have a server control and it's not inside a form tag. 

Hi,

I needed a similar solution and found this nice little thread. I used Tore's first class but made some modifications to solve the double-click problem. 

The problem occures because the variable _linkCounter is declared as private in the base class. When we don't override the rest of the methods that use this variable it won't work since the methods all use this._linkCounter.

If you use the code that Tore posted and only add the following three sections it will work perfectly. 

protected override LinkButton AddSelectedPagingLink(int pagingIndex, string text, string altText)
{
LinkButton child = this.CreatePagingLink(pagingIndex, text, altText);
child.CssClass = this.CssClassSelected;
this.Controls.Add(child);
return child;
}

protected override LinkButton AddUnselectedPagingLink(int pagingIndex, string text, string altText, bool visible)
{
LinkButton child = this.CreatePagingLink(pagingIndex, text, altText);
child.CssClass = this.CssClassUnselected;
child.Visible = visible;
this.Controls.Add(child);
return child;
}

private LinkButton CreatePagingLink(int pagingIndex, string text, string altText)
{
LinkButton button = new LinkButton();
this._linkCounter++;
button.ID = "PagingID" + this._linkCounter.ToString();
button.CommandName = pagingIndex.ToString();
button.Command += new CommandEventHandler(this.PagingItemChanged);
button.Text = text;
button.Attributes.Add("title", altText);
return button;
}

Best regards,

B 

Hi,

 I tried to use Kevin Pangs solution (since it seemed to be the most simple) , but I get a null reference error and as far as I can see thevariable "builder" is empty. Where do you assign a value to it? 

//Pontus

Sorry, my mistake, I dind't read the code properly. It works now, thanks.
